Attenuation and modal dispersion models for spatially multiplexed co-propagating helical optical channels in step index fibers: Comment

摘要

We comment on a recent paper [J Opt Laser Technol 43 (2011) 430436] in which the authors introduce dispersion and attenuation models of spatially multiplexed channels in step index multimode fibers. We consider the theoretical explanation of the model given in the paper incorrect.
